Fast Second Order Stochastic Backpropagation for Variational Inference

no code implementations NeurIPS 2015 Kai Fan, Ziteng Wang, Jeff Beck, James Kwok, Katherine A. Heller

We propose a second-order (Hessian or Hessian-free) based optimization method for variational inference inspired by Gaussian backpropagation, and argue that quasi-Newton optimization can be developed as well.

Modelling Reciprocating Relationships with Hawkes Processes

no code implementations NeurIPS 2012 Charles Blundell, Jeff Beck, Katherine A. Heller

We present a Bayesian nonparametric model that discovers implicit social structure from interaction time-series data.

Complex Inference in Neural Circuits with Probabilistic Population Codes and Topic Models

no code implementations NeurIPS 2012 Jeff Beck, Alexandre Pouget, Katherine A. Heller

This ability requires a neural code that represents probability distributions and neural circuits that are capable of implementing the operations of probabilistic inference.
